UNITE-n* srA'rss Partnr oFFicE `AnoLF VAN OANEGHEM, or* WATERLOO, IOWA SELF-CLEANING LoADNG DEVICE y.Application filed March 19, 1928. Serial No. 262,800.

.5? or .fother receptacle,.manually controllablel means `for effecting-that purpose, including coacting grab forks and devices positioned in such an operative relation thereto yas willpermit the devices to functionon the spreading 1in: apart of the forks `in discharging a load by also detaching and discharging adherent materi'al. on the forks. f v

This object I have accomplished byfthe means which .are hereinafter describedand claimed, and which are illustrated in the accompanying drawings, in which Fig. l is a front elevation of myself-cleaningloading device with its 4forks in closed.l relation, and Fig. 2 is a side elevation of the same.

i My invention is not restricted tothe precise construction and'arra'ngementofparts herein shownand described, or to the various details thereof, as the same may be modified lorfrearranged in various particulars without departing from the spirit and scope of my invention, one practical embodiment of whichl hasbeen. herein illustrated and described without attempting to'show all of the various forms and modifications in which my invention might be embodied.

-My device is particularly-adapted for use in the loading of 'a wagon or a'manurejspreader from a pile'of manure on the ground or in a stable, but I have not shown such a con- `35 veyance or receptacleorlthe devices such as may without novelty be employed to hoist the loader after filling it, moving it then overy the wagon or .receptacle for discharge thereinto,v

fixed a longitudinally disposed bar havingV its middle partbent at each side of the center Y f the device in an elongated loop 2, an eye'- bolt 3 then having its stem' fastened in the middle of the loop to project upwardly and receive a cable for lifting it after loading for transportation to and Yover a wagon.

The cross-bar 1 has at each end downwardly convergent depending and longitudinally openroll-ways 5-6 connected by an integral cross member 7, and the numeral '9 denotes headed rollers which are seated to roll in said said rollers 9 are `mounted between said furcations on connecting pintles. Below the pintle 13 thestems ll'and 12 are preferably ofV squaredy cross section, but the furcations 14 and 15' from the cross-bar portions. 33 on said stems 11 and 12 are preferably` of circular cross section to terminate in sharp pronged points, thefurcations being recurved to have vtheir pronged terminations slightly overlap when closed together.

Y To the outer furcations 14 and 15 are se cured the apertured ears 32 at about their locations of recurving. Relatively long coiled tension springs 8 are at the top connected to i the Ao'moosite terminations ofy T-hea'ds4 on the top cross bar 2 or integral therewith, and the lower `ends of said Vsprings aresecuredin the apertured ears 32.

The ears 32 may be the outturned terminations'of rigid bars 34 secured across thewouter edges of the furcations 14 and 15 to reinforce them. A short distance below'the Inedial pintle '13 aninwardly projecting horizontal arm. 16 having some upwardly directed terminalteeth 1,7 is fixed to each outer furcation 14,' and on` each side of the furcations 15 an arm 18 is medially pivoted on a stud 20 thereto, the outer ends of the arms 18 beingintegrally connected without the turcations 15 by a crosspart 21'to whose middle a .depending pull-cord 22 is secured. The in nerv termination of each arm 18 has depending teeth 19 to engage; the teeth 17 on the respective arm 16 thereunder, when the furcations 14 and 1,5 are closed together in the y position illustrated, and held in engagement yieldingly by means Yof a small coiled tension spring 25 Connected from, each arm 18 to a short fixed arm 24'thereunder'- on the .outer furcation 15. A rigidly lmounted stop-arm 23 on each said outer furcation 15 under leach arm 18 limits downward 4swinging ,of the inner toothed terminationot the arm.

Slightly below said arms 16 and v18 V-areinwardly directed arcuate arms 26 ii'Xed on'the outer furcations'lt and 15V formed 'on the same radius centered atthe p intle 13 and having longitudinal slots 27 also Yoit arcuate shape toreceive s lidinglythe pintles 28 which are secured across the topsof downwardly diver.-

V gent plates 29 which kare at the bottom secured Y, rigidly together by' means ,of cross barsv 30. Cleanerf'bars or teeth 31 have theirY upperv spaced parts welded or other-wise .fixed on the outeri'facesof they depending plates 29V to Adepend tlierefrominclinedly in the interspaces of theY furcations 14 and 15 and of suiiicient length toy permit the ywhole lower effective V lengths of said curvate-urcations to rsweep past them when the urcationsjarespread apart bythe' reactions Yof the springsS shown under tension. 'in` the figures, andwhen-.the

toothed arms 16 and -18 are disengaged.

The above described device kmay be ,sus-l pended on a cable end-'connected tothe eye.- l bolt 3'V from acarriagefof any desired typemountedfor to and' fromovements'along an elevatdtrack above 'a' wagonfbox,.manure spreader box or other receptacle, and vwith the arms 16and 18 disengaged byuse of'thepullf cord 22 and the yfurcations spreadapart. An

operator at a pile of manureor other material may then manually .close together the Yfurcations 14 and 15 in grabbing a portion of the pile thereon,` the toothed terminations of the. `arms V18 riding over Y.and mating with vthe Vtoothed ends of the karms 16`and held secured by the vsprings 25.y The springs 8 are thus placed under lengthwise `*tension pas shown.

` -The device-so loaded may thenbe hoisted,

" transported above thereceptacle, and an op- 'erator -upon ornear the latter may'useltheV Y pull-cord 22 Vto disengagethe arms 18 Yfrom.

Y the fixed arms 16, the vsprings 8 then strongly i suing.

reacting to spread apart the urcationslt and 15, discharging .the load. Simultaneously as the furcations 14 and'15 sweep" across the, in-V terposedrelatively'tixed teeth 31 thelatter disengage and discharge adherent portions of the sticky load on the furcation's. The de,- viceis then returned and lowered for another minal rollers mounted thereon, a transverse` structure containing depending inwardly inf clined rollways on which said rollers 'are mounted, resilient connections yieldingly contions belowtheir pivotal connections, and re-V leasable locking means onand to secure the*` furcations together in one relative position.
